Magnetic susceptibility measurements using an analytical scale
... This expression is usually employed in the assessment of the magnetic susceptibility. It must be pointed out that the magnitude of χ depends on the system of units used. For instance, it is possible to find χ in chemical handbooks, with cgs units. Table 1 shows the factor conversion to SI for volume ...

The magnetic field intensity H is a vector quantity, whose magnitude is given by the magnitude of the force on a unit north pole, and whose direction is the direction of the force on a north pole. Algebraically, it is conventional to represent a north pole as a positive pole and a south pole as a ne ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
